* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added
        support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
        the use of system-wide zlib.

        Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER,
        is not #undef-ed anymore. This allows the build system to define them
        depending on the configuration (typically by adding -D flags at
        compile time).

        * src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings
        in optimized mode relative to the "volatile" local variables. This was
        not a compiler bug after all, but the fact that a pointer to a volatile
        variable is not the same than a volatile pointer to a variable :-)

        the fix was to change  "volatile FT_Byte*  p"
        into                   "FT_Byte* volatile  p"

        * src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed
        compiler warnings in optimized modes

        * src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting
        any zlib function names outside of the component. This prevents linking
        problems on some platforms, when applications want to link FreeType
        _and_ ZLib together.

        * src/psaux/psobjs.c (ps_table_add): modified increment loop in
        order to implement exponential behaviour
